Hay,  What do you think about looking at how the displays are configured?   I ask because I've been trying to get a K3000m in a Dell M6700 working.  I've experienced much the same as you. However I've found that the internal LCD works, and with CE/CI, but the backlight is off.  I can connect using desktop sharing and see in ioreg that the card is initialized and working.  I can also change resolutions.  So it's getting the internal LCD's EDID okay.

However when I connect an external display on any port it hangs the graphics system(I can still SSH in).
I also read that Kepler cards for the first time support 4 displays simultaneously.  This implies some changes in the way the displays are connected and defined.  Could it be that different things need to be injected for this new setup?   One anomaly I noticed on the M6700, all the 4 displays have a 'port-number' property set to 9.  Looking at the ioreg from an nvidia retina mac.  It's port-numbers are 0, 1, 2, 3. If this is the 'port' in the same meaning as with Intel HD graphics.  There is no way they should be the same.

Hay, Yeah. I haven't made much progress.  Mainly because I can't get the K3000m to work.  I post stuff here http://www.insanelym...x-installation/ when I find anything that makes a difference.  

I've also got a Vostro 3360.  Both that and the M6700 have ALPS touch pads that don't work well.  So I'm currently trying to sort that out.  The driver is open source so it will be possible to get it working.  Just a question of time...

Hay,  I don't understand what you want.  The DSDT.aml should be in the zip.  If you need the source you can install iasl and run iasl -d to get the .dsl file.   I've updated my BIOS to A9 now. I can send you the DSDT for that if you want.

So I'm just trying the beta 10.4.8 12e36 build.    Don't know if this worked before but if I boot the machine with Optimus disabled and without any monitors attached.   I can connect to it with remote desktop.  Looking at the System Profile I can see that it's using the NVidia driver with the K3000m.  On the laptops LCD I can see that the image is there, it just the backlight is off.   Unfortunately connecting an external monitor caused the graphics system to hang.   I'm currently trying to get the backlight working with the ACPIbacklight.kext.  I've added this to the DSDT:

Method (_DSM, 4, NotSerialized)
{
	Store (Package ()
	{
		"AAPL,HasPanel", Buffer (0x04) { 0x01, 0x00, 0x00, 0x00 },
		"AAPL,Haslid", Buffer (0x04) { 0x01, 0x00, 0x00, 0x00 },
		"AAPL,backlight-control", Buffer (0x04) { 0x01, 0x00, 0x00, 0x00 },
		"@0,backlight-control", Buffer (0x04) { 0x01, 0x00, 0x00, 0x00 },
		"@0,AAPL,boot-display", Buffer (0x04) { 0x01, 0x00, 0x00, 0x00 },
		"@0,built-in", Buffer () { One }
	}, Local0)
	DTGP (Arg0, Arg1, Arg2, Arg3, RefOf (Local0))
	Return (Local0)
}

As per instructions here: http://www.insanelym...cklight-driver/

Without the above the display is detected as an AppleDisplay and not an AppleBacklightDisplay.  But still the backlight is off.

The controller methods _BCL, _BCM & _BQC only exist on the IGPU.  Don't know how this should work with the dedicated card.

Hi Sagey,
  Do you know if your K3000m is working with the NVidia driver?

I've got a Dell M6700 that also has a K3000m but I can't get it to work.  I suspect it's because the integrated HD4000 isn't completely disabled when Optimus is switched off in the BIOS. It could also be that the NVidia driver doesn't support it yet.  If it's working with acceleration on your 8770w then it has to be a problem with Optimus.   It would be really helpful if you could post a saved .ioreg file from IORegisteryExplorer.  Maybe comparing it to the M6700 will let me see why it's not working.

Thanks,
  Tim.
